    摘要： In an example, apparatus includes a first radiation source to output radiation at a first waveband and a second radiation source to output radiation at a second waveband, which is different from the first waveband. The apparatus may receive a medium having marked thereon a first colorant and a second colorant and the first and second wavebands may be selected such that an energy absorbance efficiency of the first colorant is higher than that of the second colorant at the first waveband and an energy absorbance efficiency of the second colorant is higher than that of the first colorant at the second waveband.

    摘要： Examples described herein include a print media edge repair system that includes a first repair element disposed adjacent to a media handling path to repair a leading edge of a sheet of print media as the sheet of print media moves into a position relative to a printing system associated with the print media edge repair system. The print media repair system may also include a second repair element disposed opposite the first repair element across the media handling path to repair a trailing edge of the sheet of print media as the sheet of print media moves into the position relative to a printing system.

    摘要： A method comprises applying to a substrate a layer of substantially clear solvent-based printer fluid. The printer fluid comprises an ultraviolet light absorbing substance. The method comprises irradiating the applied layer of printer fluid with an ultraviolet light to heat the solvent and cause evaporation of the solvent. The waveband of the radiation is such that heating of the solvent is substantially due to heat transfer from the ultraviolet light absorbing substance in the printing fluid.

    摘要： There is disclosed print agent drying unit 10, 20, 30 to dry print agent 40 on a substrate 14, the drying unit comprising: a substrate support 12 to support a substrate 14; an exciter 18, 28, 38 to excite a boundary layer of print agent 40 applied on the substrate 14, to thereby dissociate the boundary layer from the print agent; and a radiation source 16 to direct radiation energy to the substrate to dry the print agent. Methods of drying print agent 40 on a substrate 14 are also disclosed, including a method comprising: causing the substrate 14 to vibrate to dissociate a boundary layer of print agent 40 on the substrate 14; and heating the print agent 40 to dry the print agent 40.

    摘要： In certain examples described herein, a depositing mechanism performs an overcoat depositing operation. The depositing mechanism comprises a plurality of print head arrays. Each print head array is arrangeable in a deposit position to deposit an overcoat layer onto a substrate and a service position to enable servicing to be performed. In certain cases, an array controller causes at least one print head array of the plurality of print head arrays to be moved periodically from the deposit position to the service position according to a predefined servicing sequence during an ongoing overcoat depositing operation performed by the depositing mechanism.
